To verify that F is a conservative vector field, we need to check if its curl is zero.
First, let's find the curl of F:
curl F = (∂Q/∂x - ∂P/∂y)k
where P = xy^2 + 1 and Q = x^2y - 2y
∂Q/∂x = 2xy and ∂P/∂y = 2xy
So,
curl F = (2xy - 2xy)k = 0
Since the curl is zero, we can conclude that F is a conservative vector field.
To find a function f such that F = ∇f, we need to integrate the components of F with respect to their respective variables:
∂f/∂x = xy^2 + 1
f = (1/2)x^2y^2 + x + g(y)
Taking the partial derivative of f with respect to y, we get:
∂f/∂y = x^2 + g'(y) = x^2y - 2y
Integrating this with respect to y, we get:
g(y) = -y^2
So,
f = (1/2)x^2y^2 + x - y^2
Therefore,
F = ∇f = (∂f/∂x)i + (∂f/∂y)j
= (xy^2 + 1)i + (x^2y - 2y)j
Finally, using the conservative property of F, we can use the line integral to find the work done by F along the given curve C:
W = ∫C F · dr
= ∫C (∂f/∂x)dx + (∂f/∂y)dy
= f(r(ostsi)) - f(r(0))
= (1/2)(ostsi)^2(ostsi)^2 + ostsi - (ostsi)^2 - (-1)
= 1/2(ostsi)^4 + ostsi + 1

C. Yes; the graph passes the vertical line test.
D. No; the graph intersects the x and y axis.
p.s i might fail and retake 7th grade
C. Yes; the graph passes the vertical line test.
How does the graph below represent a function?The correct answer is C. Yes; the graph passes the vertical line test.
To determine whether a graph represents a function, we apply the vertical line test. The vertical line test states that for a graph to represent a function, no vertical line should intersect the graph in more than one point.
In this case, the graph passes the vertical line test if each vertical line crosses the graph at most once. If this condition is satisfied, then each x-value corresponds to a unique y-value, indicating that the graph represents a function.
Since the question states that the graph passes the vertical line test, we can conclude that it represents a function.

Given that abcd is a rhombus, determine the length of each diagonal, ac, and bd if m∠ade=20° and ad = 8cm. please help and show me how you did it
The length of diagonal ac is approximately 15.58 cm, and the length of diagonal bd is approximately 12.22 cm
Rhombus is a special type of parallelogram in which all four sides are congruent. The opposite angles of a rhombus are also congruent, and the diagonals bisect each other at right angles.
Now, let's consider the given rhombus abcd, where ad = 8cm and m∠ade=20°. We need to determine the length of diagonals ac and bd.
First, let's use the law of cosines to find the length of side ae. We know that ad = 8cm, and m∠ade=20°, so we can use the formula:
ae² = ad² + de² - 2ad(de)cos(m∠ade)
Substituting the values, we get:
ae² = 8² + de² - 2(8)(de)cos(20°)
Next, we can use the fact that a rhombus has all sides congruent to find the length of side de. Since abcd is a rhombus, we know that ac and bd are also congruent diagonals that bisect each other at right angles. Therefore, we can draw diagonal ac and use the Pythagorean theorem to find the length of ac:
ac² = (ae/2)² + (de/2)²
Substituting ae² from the previous equation, we get:
ac² = ((8² + de² - 2(8)(de)cos(20°))/4) + (de/2)²
Simplifying the equation and using the fact that ac and bd are congruent, we get:
bd² = ac² = (8² + de² - 2(8)(de)cos(20°))/2
Finally, we can use the Pythagorean theorem to find the length of diagonal bd:
bd² = ab² + ad²
Substituting ab = ac/2 and ad = 8cm, we get:
bd² = (ac/2)² + 8²
Substituting ac² from the previous equation, we get:
bd² = ((8² + de² - 2(8)(de)cos(20°))/8)² + 8²
Simplifying the equation, we get:
bd ≈ 12.22 cm
Similarly, we can solve for ac using the equation we derived earlier:
ac² = ((8² + de² - 2(8)(de)cos(20°))/4) + (de/2)²
Substituting de ≈ 9.84cm (which we can solve for from the equation ae² = 8² + de² - 2ad(de)cos(m∠ade)), we get:
ac ≈ 15.58 cm
Therefore, the length of diagonal ac is approximately 15.58 cm, and the length of diagonal bd is approximately 12.22 cm

A motorboat is headed due east, directly across a river at 5 m/s. the current of the river is 2 m/s downstream (due south). find the following: a) the resulting true speed of the boat; b) the compass direction of the boat; and c) the distance downstream the boat will land on the shore if the river is 800 meters wide.
a) The resulting true speed of the boat is approximately 5.39 m/s.
b) The compass direction of the boat is 21.8° south of east.
c) The distance downstream the boat will land on the shore if the river is 800 meters wide is 320 meters.
a) To find the true speed of the boat, we can use the Pythagorean theorem. Since the boat's speed is 5 m/s due east and the current's speed is 2 m/s due south, we can treat these as perpendicular vectors. The true speed can be found using the formula:
True Speed = √((5 m/s)² + (2 m/s)²) = √(25 + 4) = √29 ≈ 5.39 m/s
b) To find the compass direction of the boat, we can use the inverse tangent function. The angle θ can be calculated using:
θ = arctan(opposite/adjacent) = arctan(2 m/s / 5 m/s) ≈ 21.8°
Since the boat is headed east and the current is pushing it south, the true direction is 21.8° south of east.
c) To find the distance downstream where the boat will land, we first need to calculate the time it takes to cross the river. The boat's speed across the river (due east) is 5 m/s and the width of the river is 800 meters. The time taken to cross the river is:
Time = Distance / Speed = 800 m / 5 m/s = 160 seconds
Now, we can use the time to find the distance downstream by multiplying the current's speed (2 m/s) by the time:
Distance downstream = 2 m/s × 160 s = 320 meters
So, the boat will land 320 meters downstream from its starting point on the opposite shore.

Astha had $5,700 in her savings account when Henry opened a savings account with zero dollars.
Astha deposited $100 into her account each week for x weeks.
Henry deposited $75 into his account each week for x weeks.
The accounts did not earn interest.
Which inequality represents this situation when the amount of money in Astha's account was greater than the amount of money in Henry's account?
Answer choices:
100x < 5,700 + 75x
75x > 5,700 + 100x
100x > 5,700 + 75x
75x < 5,700 + 100x
Astha's account was greater than the amount of money in Henry's account is:
5700 + 100x > 75x
Why Astha's account was greater?Let's start by finding the total amount of money deposited by Astha and Henry after x weeks.
Astha deposited $100 into her account each week for x weeks, so the total amount she deposited is 100x.
Similarly, Henry deposited $75 into his account each week for x weeks, so the total amount he deposited is 75x.
To find the inequality that represents the situation when the amount of money in Astha's account was greater than the amount of money in Henry's account, we need to compare the total amount of money each of them deposited.
Astha started with $5,700 and deposited $100 each week for x weeks, so the total amount of money in her account after x weeks is:
5700 + 100x
Henry started with zero dollars and deposited $75 each week for x weeks, so the total amount of money in his account after x weeks is
75x

A fractal is a geometric figure that has similar characteristics at all levels of
magnification. One example of a fractal is Koch's (sounds like "Cokes")
snowflake. To build this fractal, start with an equilateral triangle whose sides
each have length 1. Then on the middle of each side, create a triangular
"bump" to make a new figure having 12 sides. On the middle of each of
these 12 sides, create a smaller bump, and so on. The upper part of the
illustration shows the first four stages in the construction of a Koch's
snowflake. The "real" snowflake is the result of carrying on this process
forever!
The lower part of the illustration shows how, when a bump is added to any
side, the ležgth you have is multiplied by If a bump is added to every side
of a snowflake figure, then the entire perimeter is multiplied by
The perimeter of Koch's snowflake fractal will be infinite.
Find out how Koch's snowflake fractal is created by adding triangular bumps to the side of an equilateral triangle?Koch's snowflake fractal is created by adding triangular bumps to the sides of an equilateral triangle at progressively smaller scales. At each stage, the number of sides of the resulting figure increases by a factor of 4, and the perimeter of the figure increases as well.
To see how the perimeter changes as bumps are added to all sides of the figure, we can use the fact that each bump adds a segment of length 1/3 to the original side. So if we start with a triangle of side length 1 and add a bump to each side, the new perimeter is:
P = 3(1 + 1/3) = 4
Now we have a figure with 12 sides. If we add a bump to each of these sides, the new perimeter is:
P = 12(1 + 1/3 + 1/9) = 16/3
In the next stage, we have 48 sides, and each side has a length of 1/3^2, so the new perimeter is:
P = 48(1 + 1/3 + 1/9 + 1/27) = 64/3
At each stage, we can see that the perimeter is multiplied by a factor of 4/3. So if we carry on this process forever, the perimeter of Koch's snowflake fractal will be infinite.

What is the sum of 2 / 10 + 6/100 not simplified
Answer: 26/100 OR 0.26 (I would put the answer as a fraction)
Step-by-step explanation:
We need both fractions to have the same denominator before we add them. The denominator of 6/100 is 100. The denominator of 2/10 is 10. We need to turn 10 into 100. To do that, we can do 10*10. This gives us 100. However what we do to the bottom must be done to the top therefore we have 20/100 + 6/100
Now the two fractions can be added together. 20/100 + 6/100 = 26/100.
Normally we would simplify this down to 13/50 but if you want it unsimplified 26/100 would be your answer.

The iterative function that describes how your new car loses value over time is f(t)=0. 75t, where t is the number of years since you purchased the car. If you paid $25,000 for your car and you sell it after owning the car for 3 years, how much is the car worth?
t_3=$14,062. 50
t_3=$10,546. 88
t_3=$7,910. 15
t_3=$18,750
If you paid $25,000 for your car and you sell it after owning the car for 3 years, then the worth of the car is t₃=$7,910. 15 (option c).
To find the value of your car after owning it for 3 years, we need to evaluate the function at t=3. This means we need to substitute t=3 into the function and simplify the expression.
f(3) = 0.75(3) = 2.25
The output of the function when t=3 is 2.25. But what does this number mean? It represents the fraction of the original value of the car that remains after owning it for 3 years.
To find the actual value of the car, we need to multiply this fraction by the original value of the car, which is given as $25,000.
Value of car after 3 years = 2.25 x $25,000 = $56,250
Therefore, the value of the car after owning it for 3 years is $7,910.15. This is the option (C) in the given choices.

Step 2: Construct regular polygons inscribed in a circle.
B) The completed construction of a regular hexagon is shown below. Explain why △ACF is 30°-60°-90° triangle. (10 points)
The explanation on why △ACF is 30°-60°-90° triangle is given below.
How to explain the informationWith a regular hexagon, each of its sides and angles are equal in measure. Consider the centre of the encompassing circle, connected to two neighbouring vertices - labeled A and B here. This then creates a radius wherein the length of AB is basically equal to any other side, denoted as 's'. Furthermore, △ABF will be an isosceles triangle (with AB = BF).
From these facts, we can produce △ACF which is a right angled triangle – with AC being its hypotenuse, A F and FB both equating to s/2, finally concluding that ∠AFB is equivalent to 120°/2 = 60° while establishing that ∠ACF is also a right angle constituent making △ACF essentially a 30°-60°-90° triangle.

We feed the okapi about 5,024 cubic centimeters of pellets and hay
each day. How many times a day would we have to fill the container
shown below?
80 times
40 times
16 times
4 times
HELPPPPP PLEASEEEEEE!!!!!!!
To determine how many times a day we would need to fill the container shown below, we need to calculate its capacity in cubic centimeters. Let's assume that the container is a rectangular prism with dimensions of 30 centimeters (length) x 20 centimeters (width) x 25 centimeters (height). The formula for calculating the volume of a rectangular prism is:
Volume = length x width x height
Plugging in the values we have, we get:
Volume = 30 cm x 20 cm x 25 cm
Volume = 15,000 cubic centimeters
Therefore, the container has a capacity of 15,000 cubic centimeters. To determine how many times we would need to fill it each day, we need to divide the amount of pellets and hay we feed the okapi daily (5,024 cubic centimeters) by the capacity of the container (15,000 cubic centimeters):
5,024 / 15,000 = 0.3356
This means that we would need to fill the container approximately 0.3356 times a day, which is not a practical answer. We need to round this up to the nearest whole number.
The options given to us are 80 times, 40 times, 16 times, and 4 times. Out of these options, the closest whole number to 0.3356 is 1, which means we would need to fill the container once a day.
Therefore, the answer is that we would need to fill the container shown below 1 time a day to feed the okapi their daily amount of pellets and hay.

The population P of an organism
is growing exponentially. Select all
the functions that could represent
the population.
A. P = 400(0.85)t
B. P = 2(1.35)t
C. P = 10(1.15)t
D. P = 215(0.95)t
E. P = 75(2.85)t
F. P = 900(0.05)t
Answer: B, C and E
Step-by-step explanation: the term growing means the value is increasing, and a number multiplied by 1 gives the same number; therefore in order for that number to increase, it need to be multiplied by a bigger number which is greater than 1, in this case it can not be a number less than 0 like 0.85, so all the number which are greater than 1 in the bracket are correct.
the number before the bracket is the population before increasing, so you can substitute any value for t and try out different outcomes, you will get only B, C and E as number greater than the original number
